Nobody can fill the extra-large Adidas sneakers favored by the Beastie Boys, but the Roots, Kid Rock and Travie McCoy of the Gym Class Heroes nobly did their best last month when the B-Boys were inducted into the Rock and Roll Hall of Fame in Cleveland, Ohio. Adam "MCA" Yauch called in sick at the 11th hour -- Yauch's mom later revealed he was admitted into the hospital that very night as he continued to battle cancer, a battle that sadly ended Friday (May 4) when Yauch passed away at the age of 47.

With the Beasties unable to perform, Kid Rock, Travie McCoy and Roots MC Black Thought hit the Cleveland stage (with the rest of the Roots backing them instrumentally) on April 14 properly attired -- head-to-toe in green Adidas track suits -- and went for it, performing a medley of Beasties hits.

Opening with longtime Beasties DJ Mixmaster Mike working the decks (and adding a direct link to the band being honored), the stand-in trio quickly launched in to 'No Sleep Till Brooklyn,' and then flowed through snippets of 'So What'cha Want,' 'Sabotage,' The New Style' and 'Rhymin’ & Stealin’.'

While energetic and pretty note-for-note dead-on, their set also unintentionally highlighted just how one-of-a-kind the Beasties are. All three rappers nailed their parts, but the songs just don't sound quite right without MCA, Mike D and Ad-Rock rocking the mic. They can't, they don't and they won't stop. Period.

The five-and-a-half-hour long Rock Hall induction ceremony didn't air live, but instead was edited down to a more palatable two-and-a-half-hour highlights reel that was broadcast Saturday night (May 5) on HBO. Professionally shot footage from that special has yet to surface online -- we're looking and will throw it up here once it does -- but in the meantime there's still plenty of fan-shot footage out there on YouTube. It's all a little shaky, but the sound is stellar and you still get the drift. Check it out below.
